Description

Technical area

The present invention relates to a patient lift device having at least one on a - preferably mobile - frame by means of at least one lifting or pivoting drive (hereinafter referred to as drive) pivotally and / or linearly movable support arm, provided on the support means for raising or lifting a patient are.

State of the art

Patient lifts and raising aids have been used in clinics, nursing homes and home care for decades. Depending on the particular physical activity of the patient, three types of devices are used:

Type 1 crane-like patient lifts are known, which are used in case of substantial inactivity of the patient and completely lift the patient by means of suitable means of support. Such a design show the published patent applications GB 2 281 062 A . EP 0 236 284 A2 ,

Type 2 is used when the patient still has a low level of residual stamina. In this case, this is supported by a Aufrichthilfe eg from the bed or the wheelchair by an applied in the pelvic / buttocks Aufrichtgurt when getting up in the vertical, as for example, from the utility model DE 20 2009 004 889 U1 is known. The Gurtansatz takes place here in about the middle of the body; the feet have contact with the ground.

The type 3 is suitable, if the patient in addition to residual power also has enough body tension (tonus) that he does not collapse or bend in the middle of the body when standing upright in the area of the upper back / armpits when getting up or standing. This type of lift offers the advantage that, as a result of the buttocks not being strapped in the toilet, the patient's pants can be pulled down and pulled back by the caregiver more easily. The patents DE 600 17 617 T2 and DE 699 33 582 T2 show exemplary solutions.

Meanwhile, combinations of the above-mentioned types of equipment are known, for example. Can a patient lift according to the utility model DE 203 18 969 U1 by simply converting from the pure lift (feet have no contact with the ground) in a Aufrichthilfe (belt attachment in the area armpits / shoulder) to be converted, the feet have a ground contact.

On the one hand, the disadvantages of the hitherto known solutions consist in the fact that only one type always fits within the patient profile within a specific care period. If the condition changes - be it for better or for worse - the existing lift must be replaced by a more suitable device to ensure optimal care. This not only causes higher overall equipment costs but also additional logistics costs with a corresponding expenditure of time, since several jobs have to be switched on during procurement (medical service of the health insurance funds, cost unit, medical supply store, manufacturer). On the other hand, there are always patients with different care profiles in clinics, homes etc. With optimal care, the right type of lift must always be available at the right place for every patient. For cost reasons, this is at most isolated possible. In practice, due to time constraints, it is not long before searching for an appropriate type of device, if any, but instead either manually implementing the patient - at the expense of the health of the nursing staff, or using a wrong lifter, eg Type 1, in the presence of residual patient activity but counter-acting.

With the utility model DE 203 18 969 U1 it is possible to care for the patients with the appropriate care profile (according to device type 1 and 3). However, the patient with residual standing ability, but pressure-sensitive in the armpit / shoulder area, in which a large part of the body weight rests when pulling up the belt, can not be optimally supplied with this type of device.

Presentation of the invention

The present invention is based on the object to further develop a patient lift device by the following requirements are met with a single device by simply retooling: a) patients with / without low mobility by means of toilet or sling lift; b) assisting patients with residual standing when straightening with a harness attachment in the area of the buttocks / pelvis during erection; c) Support patients with high stamina and sufficient resilience in the middle of the body by means of a belt attachment in the area of the armpit / shoulder when straightening up.

According to the invention the above object is achieved with the features of claim 1. Advantageous embodiments of the patient lift device according to the invention are specified in the subclaims.

Thereafter, a patient lift device of the type mentioned above is characterized in that on the support arm and / or on the frame at least one means is provided which causes the lifting dimension of the support means in a fixed ratio to the amount of movement of the lifting or pivoting drive and / or is in a defined relationship to the pivoting and / or linear movement dimension of the support arm or that can be regulated by means of the device such a variable ratio.

According to a particularly preferred embodiment of the invention, the patient lift device for this purpose has a column movably arranged on a column, wherein for deflection desselbigen a preferably electric drive is provided, which is fixed at one end to the column and at the other end to the support arm. The device according to the invention is preferably realized in such a way that one end of at least one kind of traction means (preferably a pull rope) and at least one fixed roller are fixedly connected to the column via a traverse. According to the pulley principle, the pull rope first circulates a loose roller attached to the support arm, then the fixed roller, in order to be subsequently connected to the buttock lap belt surrounding the patient.

After activation of the drive, the support arm moves, the traction cable follows this movement with translation and thus supports the patient by the force acting on the buttocks lap belt pulling force when standing up. This allows a patient to be cared for in accordance with the device type 2 shown above.

If the patient has sufficient body tension in the middle of the body and sufficient stamina, according to a further embodiment of the invention, the device type 3 conversion is applied by applying to the patient an underarm shoulder strap whose ends are attached directly to the support arm , Of course it is possible, either for additional safety reasons or for other reasons, to put both straps on the patient at the same time (buttock, pelvic and shoulder harness). The two straps do not interfere.

If the patient does not have any activity of his own (mobility), instead of the above-mentioned straps, a carrying or toilet tissue is wrapped around the thighs, buttocks and back. At the ends of the carrying or toilet tissue is directly on the support arm or on a provided in a further embodiment of the device - preferably telescopic - Extension of the same suspended, so that the patient can be lifted in the traditional sense in sitting posture, thus the device type 1 is enough. The extension may also be designed to be extensible in addition to a telescopic training in any other known manner. Thus, for example, an extension by means of two adjacent rods, rails or the like is conceivable, which in defined areas (eg. By means of a screw or plug connection) can be fixed to each other.

In a further embodiment of the invention, it is possible to provide a substantially vertically and linearly to the column moving support arm instead of the rotatable support arm. This means that all three types of devices can be realized as well.

The advantages of the patient lift device according to the invention are versatile: a) the design according to the invention of the patient lift device makes it possible to generate a significant increase in functions with a single base device and thus decisively increase the versatility of use; b) this makes it much cheaper than several single-function devices; c) a single drive and a single control and supply unit for all 3 types of equipment is sufficient; d moreover, a quick conversion is given.

Furthermore, in Fig.1 a the bottom view "ZZ" shown, from which the support arm 2, the tension cables 8 and 9 and the pulleys 4,6 and the pulleys 5,7 are visible. In a sectional manner, the column 1 with the drive 13 also emerges from this. The attached to the column 1 control and supply unit 16 is not shown for the sake of clarity.

In the Fig.2 illustrated advantageous embodiment of the invention shows a mounted on a frame 100 column 1, at whose upper end a support arm 2 is mounted in the axis of rotation 12 so that a rotational movement of the support arm 2 is made possible relative to the column 1 in the vertical direction. For deflection for a preferably linear drive 13 is provided, which is connected with its lower end at the suspension point 14 on the column 1 and with its upper suspension point 15 with the support arm 2 is. The patient is enveloped by an armpit shoulder strap 60 whose ends 61 and 62 are hooked on the support arm 2.

If a control signal is transmitted to the control and supply unit 16 via the operating part 17, the drive 13 moves out and thereby moves the support arm 2 about the axis of rotation 12. As a result, a pulling force acts on the armpit shoulder belt 60 which assists the patient during the erection process ,

In the Fig.2 Contoured contours show the in the extended position located support arm 2 ', the armpit shoulder strap 60' and in an upright position the patient.

In the Figure 3 shown advantageous embodiment shows a mounted on a frame 100 column 1, at whose upper end a support arm 2 is mounted in the axis of rotation 12 so that a rotational movement of the support arm 2 relative to the column 1 in the vertical direction is made possible. For deflection for a preferably linear drive 13 is provided, which is connected with its lower end at the suspension point 14 on the column 1 and with its upper suspension point 15 with the support arm 2. The patient is surrounded by a sling 70 on the thighs, buttocks and back. At least one arranged in the support arm 2 telescopic tube 20 and 21 is provided at one end with hooks 71/72, in which the sling 70 is hooked with its respective ends. The enclosing sling 70 may also be designed for toilet use (also) either with hole in the buttocks area or 2-part (first strap under the thighs and second strap on the back), wherein in the 2-part design, the suspension for both straps also on the telescopic extension is arranged.

If a control signal is sent to the supply and control unit 16 via the operating part 17, the drive 13 moves, thereby moving the support arm 2 about the axis of rotation 12, whereby the patient is lifted in the sling 70 into an upper position. This upper position is dotted for the support arm 2 ', the telescopic tube 20' and 21 ', the belt 70' and the patient shown.

In further embodiments of the invention, on the one hand, the cross member 3 on the column 1 vertically adjustable and the roller 5 on the support arm 2 at different locations (eg. At designated slots) individually positioned to thereby provide the patient lift device even more flexibility.

The patient lift device according to the invention is not limited in its execution to the above-mentioned preferred embodiments. Rather, a variety of design variations are possible, which make use of the solution shown even with fundamentally different type of execution.
